MEASURED JET NOISE COMPARED TO CALIFORNIA NOISE CODES AND HEALTH LIMITS

In December 1971, maximum allowable limits on aircraft noise at California airports effective in the Public Utilities Code (PUC). Noise-exposure limits are specified in terms of a base parameter, Single Event Noise Exposure Level (SENEL), which is an integration of A-weighted noise level with time. Measurements of conventional jet aircraft landing-noise levels at Los Angeles International Airport (LAX) were made and compared to the PUC SENEL limits, to the "standard" SENEL values used for mapping community noise exposure zones, and to noise limits for hearing and health conservation. The measurement survey indicated that at 1 NM from landing threshold, the standard SENEL limits were exceeded by 50 to 15 dB 50% of the time, and the California SENEL limits were exceeded about 50% of the time. Data from special flight tests for the FAA indicated that the implied SENEL limits would be violated about 35% of the time. If violators were cited according to the PUC ($1000 per violation), the resulting fines for landing operations would be about $200,000 per day, or $70 million per year, at LAX.
